Day27:pom.xml設定

今天的目標是要配置pom.xml。

只要在pom.xml這隻裡面配置好dependency,就會幫你把你需要的jar檔載下來。

要先在pom.xml裡面加入下面的設定。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

這邊的設定包含了很多,可以把不需要的部分拿掉,其中設定了有

1.JSTL,前端會使用的C標籤,所以我把它加進去
2.SLF4J以及Log4j,這是用來記錄Log的,不需要可以拿掉
3.MySQL Connector,基本上是一定會有,如果需要換資料庫在做調整即可

設定完後,記得存檔,然後到專案上按右鍵->Maven->Update Project->OK
在打開會發現已經幫你把jar檔都載進來了,連帶剛剛的錯誤也都消失了。

以上是pom.xml設定的部分。
